This Amendment No. 3 to Tender Offer Statement on Schedule TO is being filed by Corning and amends and supplements certain provisions of Corning's Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission (the "SEC") on May 7, 2003, as amended on May 20, 2003 and June 5, 2003 (as amended and supplemented, the "Schedule TO") and Corning's offer for the Notes set forth in the Offer to Purchase for Cash Up to $800,000,000 Aggregate Principal Amount at Maturity of its Outstanding Zero Coupon Convertible Debentures Due November 8, 2015 (CUSIP No. 219350 AJ 4) (as amended and supplemented, the "Offer to Purchase"), and the related Letter of Transmittal, as amended (as amended and supplemented, the "Letter of Transmittal") which, together with the Offer to Purchase, constitute the "Offer") and both of which are filed as Exhibits to the Schedule TO with the SEC. The Offer expired at 12:00 midnight, Eastern Time, on June 4, 2003.
